JavaScript - How To Make Expandable Para Or Link?
I want to create a link which doesn't takes you to anew page but just expands to show it's information . Exactly like the one in FAQs where you click the question and the page expands to show you the answer.
Similar TutorialsI enclose code that should work. What to change that this code will work. I used prototype.js I have a button given like this: <a href="test.php"><input class="test" type="test"></a> I have a CSS that defined the button as an image, and on hover the button changes. However, on hover, I'd like there to come a drop down that for example link to test 1, test 2, test 3. Is this possible? Thank you! Is there any way to make a link show if javascript is being used to hide it? This is the javascript code that is hiding the link: Code: <a href="javascript:void(0)" class="show-hide-link action-link"> Hi-- I have a link that has an mp3 sound as its href: Code: <a href="sounds/genealogy.mp3" class="track track-default">this is a link</a> Unfortunately, I also need that same link to go to a part on the site (href=#greenhouse) so that the sound plays on that part of the site. Does anyone know how to accomplish this? I am imagining it would be with javascript, but honestly, I do not know. Any help would be greatly appreciated. Many thanks...! Please help me make the links below open in the "top" or "parent" frame of a window. For example, in HTML, you would use
Code: <a href="URL" target="_top">LINK</a> I just do not know how to make the links below perform in the parent window. (or even a new window if that is only possible.) Code: var $el, $tempDiv, $tempButton, divHeight = 0;
$.fn.middleBoxButton = function(text, url) {
return this.hover(function(e) {
$el = $(this).css("border-color", "white");
divHeight = $el.height() + parseInt($el.css("padding-top")) + parseInt($el.css("padding-bottom"));
$tempDiv = $("<div />", {
"class": "overlay rounded"
});
$tempButton = $("<a />", {
"href": url,
"text": text,
"class": "widget-button rounded",
"css": {
"top": (divHeight / 2) - 7 + "px"
}
}).appendTo($tempDiv);
$tempDiv.appendTo($el);
}, function(e) {
$el = $(this).css("border-color", "#999");
$(".overlay").fadeOut("fast", function() {
$(this).remove();
})
});
}
$(function() {
$(".widget-one").middleBoxButton("Action Games","action.htm");
$(".widget-two").middleBoxButton("Adventure Games", "adventure.htm");
$(".widget-three").middleBoxButton("Arcade Games", "arcade.htm");
$(".widget-four").middleBoxButton("Puzzle Games", "puzzle.htm");
$(".widget-five").middleBoxButton("Sport Games", "sport.htm");
$(".widget-six").middleBoxButton("Search Games", "searchgames.htm");
});
Thank you very much for your help!!! Hey guys, I own an online internet radio station and I have many different way which people can tune in. One way is the browse 'n' play feature. The browse 'n' play feature allows you to browse the net at the same time as being tuned into the radio. Below, I have installed an 'Expandable Sticky Bar' which is used for the radio panel. http://www.dynamicdrive.com/dynamici.../stickybar.htm What I am trying to do, is simply add that bar on every page my visitors visit. So, when the listen chooses 'Browse 'n' Play' I want a new window or tab to open, with Google and my bar at the bottom. I cannot figure out how I could do this, any ideas on how I could make this happen? Thanks. I just got this problem when I try to add the expandable divs in my webpage. However when I click the divs on the page, I can't see the rest of my content. This is my page, does anybody know what happened with my code??!! http://www.calibredesign.com/clients..._news_new.html the divs are on the button of the page. Thanks!! hi, i got a expandable menu that is working. i wonder if there is any way to make the links show as html and css if the user has disabled javascript i my code including javascript and css <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script language="JavaScript" type="text/JavaScript"> <!-- menu_status = new Array(); function showHide(theid){ if (document.getElementById) { var switch_id = document.getElementById(theid); if(menu_status[theid] != 'show') { switch_id.className = 'show'; menu_status[theid] = 'show'; }else{ switch_id.className = 'hide'; menu_status[theid] = 'hide'; } } } //--> </script> <style type="text/css"> .menu1{ margin-left:25px; padding-left:20px; padding-top:2px; padding-bottom: 2px; display:block; text-decoration: none; color: #000000; height: 20px; width: 200px; background-color: #03C; border: thin solid #FFF; } .submenu{ background-image: url(images/submenu.gif); display: block; height: 19px; margin-left: 38px; padding-top: 2px; padding-left: 7px; color: #333333; } .hide{ display: none; } .show{ display: block; } </style> </head> <body> <a class="menu1" onclick="showHide('mymenu1')">Menu 1</a> <div id="mymenu1" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu2')">Menu 2 </a> <div id="mymenu2" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu3')">Menu 3 </a> <div id="mymenu3" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu4')">Menu 4 </a> <div id="mymenu4" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu5')">Menu 5 </a> <div id="mymenu5" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> </body> </html> Hi, I'm completely new to using JavaScript having never used it before so please forgive me if this is ridiculously easy to solve.

Any help you can give would be greatly appreciated. Many thanks Ok so im new to javascript and I have a button in an interface for an app. It's like drag and drop and i want this button to link you to a certain website searching for what the user types in the searchField1 box. The button is button16. Such as you type dogs into the text box and you click the google button among other search engines and it will redirect you to a google search doing a search for dogs. But how do I make this button search google and search for whats in searchField1. I would really appreciate the help. Im looking everywhere to learn this but just cant find it. If you could tell me how or send me a link to a tutorial that would be great. Thanks! Here is the code: I don't know where and what to add to do that. Please help. Hello, I'm pretty new to JS but I can script a few things. I'm using a pre-written script, but trying to add a functionality that uses my + and - images to indicate whats whether the list is expanded or not. It works on the first click. The symbol starts as a plus, you click it and it expands and goes to minus. After that the list maintains functionality (for the most part) but doesn't continue changing symbols back and forth. I've pored over the script for HOURS but I can't find the solution. Working Link Example My written JS: Code: // JavaScript Document
var expandables = new Array();
expandables[0] = "expand_northeast";
expandables[1] = "expand_southeast";
expandables[2] = "expand_midwest";
expandables[3] = "expand_southwest";
expandables[4] = "expand_west";
var clickCounter = 0;
function expand(current) {
//add height to the containing div
if(clickCounter<=1) {
var newHeight = document.getElementById('region_us').offsetHeight + 187;
document.getElementById('region_us').style.height = newHeight.toString() + 'px';
clickCounter+=1;
}
//get the section name
var section = current.split('_')[1];
for ( var i=0; i<expandables.length; i++ ){
if(document.getElementById(expandables[i]).id.indexOf('collapse') != -1){ //if it has collapse in id string
var tempSection = expandables[i].split('_')[1]; //parse just the region
document.getElementById(expandables[i]).id='expand_' + tempSection; //change the id to expand / plus symbol
expandables[i] = document.getElementById('expand_' + tempSection).id; //make the change in the array as well
}
}
document.getElementById(current).href='javascript:animatedcollapse.show(\'stats_'+ section + '\');';
document.getElementById(current).onclick=function() {collapse('\'collapse_'+section +'\'');};
document.getElementById(current).id="collapse_" + section + "";
for (x in expandables)
{
if(expandables[x] == current){
expandables[x] = document.getElementById('collapse_' + section).id;
}
}
//alert(expandables);
}
function collapse(current) {
var section = current.split('_')[1];
//alert(current);
current = ("expand_"+section);
document.getElementById(current).href='javascript:animatedcollapse.hide(\'stats_'+ section + ');';
document.getElementById(current).onclick=function() {expand('"expand_'+section+'"');};
document.getElementById(current).id='expand_' + section;
for (x in expandables)
{
if(expandables[x] == current){
expandables[x] = document.getElementById('expand_' + section).id;
}
}
}

Thanks guys! Trying to put my finger on how to achieve this result. About half way down on the page linked below you'll see "Recent - Comments - Popular - Tags" this table expands when you rollover and stays expanded while allowing you to populate the different content. Any help would be greatly appreciated, not even sure if I'm in the right forum. http://thedailydisney.com/blog/2010/...magic-kingdom/ Thanks for the time. Will I am building an elearning site where the user is taken through a series of dynamically driven pages to refine their choices. I am using php amd mysql to populate a series of tables but on the last page the table gets very long so i am trying to make the table expandable. I found this and this on http://www.javascripttoolbox.com/jquery/ and it's proving helpful but i need a little help taking it a step further. I also found this to be useful for anyone else who is trying to do the same thing: http://www.jankoatwarpspeed.com/post...nd-plugin.aspx FROM JAVASCRIPTTOOLBOX A common UI is to have a table of data rows, which when clicked on expand to show a detailed breakdown of "child" rows below the "parent" row. The only requirements a 1. Put a class of "parent" on each parent row (tr) 2. Give each parent row (tr) an id 3. Give each child row a class of "child-ID" where ID is the id of the parent tr that it belongs Original code: Code: $(function() {
$('tr.parent')
.css("cursor","pointer")
.attr("title","Click to expand/collapse")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
});
$('tr[@class^=child-]').hide().children('td');
});
This works great but my parent and child rows all contain checkboxes and If i try and check the checkboxes in the master rows the child rows associated with that master row expand and contract. I have added an extra cell to each row and i'm using a css class to add an arrow image to each master row but i am new to Javascript so i am not sure what i am doing. My code now looks like this: Code: $(document).ready(function() {
$('tr:not(.parent)').hide();
//$('tr.parent')
$('.arrow')
.css("cursor","pointer")
.attr("title","Click to expand/collapse")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
$(this).toggleClass("up");
});
});
So far the arrow image is toggling but i can't seem to work out how to get the .click function to affect the whole row and not just the image. Can anybody help me? Thanks Hello, I was wondering whether it is possible to expand and collapse forum categories using JavaScript. The forum board I am using is phpBB. Hi, I have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice. This is my criteria: If someone chooses checkbox number 1, they cannot choose any other checkbox. If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below. One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed. I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work. Does anyone know how to accomplish all of this? Thank you in advance! Hey thanks in advance to anyone who can take a peak at my code and hopefully point me in the correct direction. I have been working on my final project in my javascript class for a bit, and there are a few erros I cant seem to find through firebug or error console. It is due this evening at midnight, so anyone that could help, I really need this assignment for a decent grade. Basically there are two issues so far, one needs to be solved so the other can be as well. First, line 103 - 105 should create a hyperlink to the specified id, but is doesn't return a number. so the link goes no where it is this code: PHP Code: //create hypertext link to the section heading var linkItem = document.createElement("a"); linkItem.innerHTML = n.innerHTML; linkItem.href = "#" + n.id; Next I belive there is a problem with the function expandCollapseDoc(), that might fix itself when the other problem is solved. The document should expand and collapse with the menu. Here is my javascript code: PHP Code: /* New Perspectives on JavaScript, 2nd Edition Tutorial 7 Tutorial Case Author: Mike Cleghorn Date: 2-15-10 Filename: toc.js Global Variables: sections An array contain the HTML elements used as section headings in the historic document Functions List: addEvent(object, evName, fnName, cap) Adds an event hander to object where evName is the name of the event, fnName is the function assigned to the event, and cap indicates whether event handler occurs during the capture phase (true) or bubbling phase (false) makeTOC() Generate a table of contents as a nested list for the contents of the "doc" element within the current Web page. Store the nested list in the "toc" element. levelNum(node) Returns the level number of the object node. If the object node does not represent a section heading, the function returns the value -1. createList() Goes through the child nodes of the "doc" element searching for section headings. When it finds a section heading, a new entry is added to the table of contents expandCollapse() Expands and collapse the content of the table of contents and the historic document expandCollapseDoc() Goes through the child nodes of the "doc" element determining which elements to hide and which elements to display isHidden(object) Returns a Boolean value indicating whether object is hidden (true) or not hidden (false) on the Web page by examining the display style for object and all its parent nodes up to the body element */ function addEvent(object, evName, fnName, cap) { if (object.attachEvent) object.attachEvent("on" + evName, fnName); else if (object.addEventListener) object.addEventListener(evName, fnName, cap); } addEvent(window, "load", makeTOC, false); var sections = new Array("h1","h2","h3","h4","h5","h6"); var sourceDoc; //document on which TOC is based on function makeTOC(){ var TOC = document.getElementById("toc"); TOC.innerHTML = "<h1>Table of Contents</h1>"; var TOCList = document.createElement("ol"); TOC.appendChild(TOCList); sourceDoc = document.getElementById("doc"); //generate list items containing section headings createList(sourceDoc, TOCList); } function levelNum(node) { for (var i = 0; i < sections.length; i++) { if(node.nodeName == sections[i].toUpperCase()) return i; } return -1; //node is not section heading } function createList(object, list) { var prevLevel = 0; //level of the pervious TOC entry var headNum = 0; //running count of headings for (var n = object.firstChild; n != null; n = n.nextSibling) { //loop through all nodes in object var nodeLevel = levelNum(n); if (nodeLevel != -1) { //node represents a section heading //insert id for the section heading if necessary headNum++; //create list item to match var listItem = document.createElement("li"); listItem.id = "TOC" + n.id; //create hypertext link to the section heading var linkItem = document.createElement("a"); linkItem.innerHTML = n.innerHTML; linkItem.href = "#" + n.id; //append the hypertext to the list entry listItem.appendChild(linkItem); if (nodeLevel == prevLevel) { //append the entry to the current list list.appendChild(listItem); } else if (nodeLevel > prevLevel) { //append entry to new nest list var nestedList = document.createElement("ol"); nestedList.appendChild(listItem); list.lastChild.appendChild(nestedList); //add plus/minus box beffore the text var plusMinusBox = document.createElement("span"); plusMinusBox.innerHTML = "--"; addEvent(plusMinusBox, "click", expandCollapse, false) nestedList.parentNode.insertBefore(plusMinusBox, nestedList.previousSibling); list = nestedList; prevLevel = nodeLevel; } else if (nodeLevel < prevLevel) { //append entry to a higher-level list var levelUp = prevLevel - nodeLevel; for (var i = 1; i<= levelUp; i++) {list = list.parentNode.parentNode;} list.appendChild(listItem); prevLevel = nodeLevel; } } } } function expandCollapse(e) { var plusMinusBox = e.target || event.srcElement; var nestedList = plusMinusBox.nextSibling.nextSibling; //Toggle the plus and minus symbol if (plusMinusBox.innerHTML == "--") plusMinusBox.innerHTML = "+" else plusMinusBox.innerHTML = "--"; //Toggle display of nested list if(nestedList.style.display == "none") nestedList.style.display = "" else nestedList.style.display = "none"; //expand/collapse doc to match TOC expandCollapseDoc(); } function expandCollapseDoc() { var displayStatus = ""; for (var n = sourceDoc.firstChild; n != null; n = n.nextSibling) { var nodeLevel = levelNum(n); if (nodeLevel != -1) { //determain display status of TOC entry var TOCentry = document.getElementById("TOC" + n.id); if (isHidden(TOCentry)) displayStatus = "none" else displayStatus = ""; } if (n.nodeType == 1) { //apply to current status for the node n.style.display = displayStatus; } } } function isHidden(object) { for (var n = object; n.nodeName != "BODY"; n = n.parentNode) { if (n.style.display = "none") return true; } return false; } the html was too long, so i uploaded it to my webspace you can check out the almost working version at http://www.kinetic-designs.net/final/usconst.htm Again thank you so much! Any questions just ask! Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael |
